The Inverse First Passage Time Problem for killed Brownian motion
Boris Ettinger, Alexandru Hening, Tak Kwong Wong
The classical inverse first passage time problem asks whether, for a Brownian motion and a positive random variable , there exists a barrier $b:\mathbb{R}_+\to…
A sharp counterexample to local existence of low regularity solutions to Einstein's equations in wave coordinates
Boris Ettinger, Hans Lindblad
We are concerned with how regular initial data have to be to ensure local existence for Einstein's equations in wave coordinates. Klainerman-Rodnianski and Smith-Tataru showed that…
Killed Brownian motion with a prescribed lifetime distribution and models of default
Boris Ettinger, Steven N. Evans, Alexandru Hening
The inverse first passage time problem asks whether, for a Brownian motion and a nonnegative random variable , there exists a time-varying barrier such that $\mathbb{P}\…
Well-posedness of the equation for the three-form field in the eleven dimensional supergravity
Boris Ettinger
We analyze the equations for the three-form field - a system of semi-linear gauge-invariant wave equations which arises in the theory of eleven dimensional supergravity. We prove t…
Global Existence and Uniqueness of Weak Solutions of 3-D Euler Equations with Helical Symmetry in the Absence of Vorticity Stretching
Boris Ettinger, Edriss S. Titi
We prove uniqueness and existence of the weak solutions of Euler equations with helical symmetry, with initial vorticity in under "no vorticity stretching" geometric c…
Linear versus Non-linear Acquisition of Step-Functions
Boris Ettinger, Niv Sarig, Yosef Yomdin
We address in this paper the following two closely related problems: 1. How to represent functions with singularities (up to a prescribed accuracy) in a compact way? 2. How to reco…
